Tools: check_domain
check_domain | Audit the email-authentication DNS records of a domain. Returns a 0–100 score and A–F grade (MX 10, SPF 25, DMARC 30, DKIM 25, BIMI 10, plus up to 5 bonus points for MTA-STS and TLS-RPT, capped at 100), each check's status, published record, findings and recommended fixes, and a link to the full report. Read-only: it only queries public DNS and the domain's public MTA-STS policy file. Same engine params: domain*, dkim_selector, include_raw |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
